JOSEPH SAMPSON, OF SIOUX FALLS, SOUTH DAKOTA.

EXCAVATOR AND LOADER.

SPECIFICATION forming part of Letters Patent No. 779,239, dated January3, 1905.

Application filed April 21, 1904. Serial No. 204,271.

To ctZZ whom it may concern.-

Be it known that I, J OSEPH SAMPSON, a citizen of the United States,residing at Sioux Falls, in the county of Minnehaha and State of SouthDakota, have invented certain new and useful Improvements in Excavatorsand Loaders; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention relates to a dirt excavator and loader, and has for itsobject to provide an apparatus of this kind which may be mounted upon anordinary vehicle-body and employedto excavate the earth while thevehicle is in motion and discharge the same into a dirtwagon drivenalongside the excavator and loader.

In the accompanying drawings, Figure 1 is a side elevation of anexcavator and loader embodying my invention. Fig. 2 is a top plan viewthereof. Fig. 3 is a vertical longitudinal section. Fig. 4: is across-section.

Referring to the drawings, 1 represents the body of a vehicle of anyconstruction suitable for the purpose. Mounted upon this body is a frameor superstructure 2, to which is pivotally connected at 3 the upper endof an inclined excavator-frame 4, carrying at its upper and lower endsshafts 5 and 6, around which passes the endless excavator-belt 7,provided with the scoops or shovels 8. The ex cavator-frame extendsdownward through an opening in the bottom of the body 1 to a point inclose proximity to the ground-surface, so that when the excavator-belt 7is in motion the shovels 8 will scoop up the earth and convey the sameto the upper end of the excavator at a suitable elevation above the topof the body 1.

On the upper shaft 5 of the excavator is a sprocket-wheel 9, whichreceives motion from a double sprocket-wheel 10, mounted upon the body1, through the medium of a connectingchain 11, which engages one of thesprocketsurfaces of said wheel 10. The other sprocketsurface of thewheel 10 is engaged by the upper stretch of a traveling chain 12, thelower stretch 13 of which is adapted to engage and receive motion from asprocket-wheel let, fixed to, one of the rear wheels of the vehicle.Between its upper and lower stretches the chain 12 is guided at pointsin front and rear of the plane of the wheel 10 by idlers 15 and 16, thelatter being mounted on a suitable adjusting device 17, whereby it maybe raised to lift the lower lead 13 of the chain 12 out of engagementwith the sprocket-wheel 14, and thus arrest the motion of the gearingand stop the excavator.

To the adjusting device 17 is attached one end of a chain 18, whichpasses over one or more guide wheels or pulleys 19 to the front of thebody 1, where it is connected to the operating-lever 20, disposed inproximity to the drivers seat to enable the driver to conveniently throwthe chain 12 into and out of gear.

The excavator is adapted to be lowered and raised for the purpose ofthrowing the same into and out of operation and to this end is connectedat its lower end to a chain or analogous connection 21, passing overguide pulleys or wheels 22 and 23, located, respectively, on the frontaxle and body of the vehicle and connected at its forward end to a lever24, disposed alongside of the lever 20, whereby the driver mayconveniently adjust said excavator to throw the same into and out ofoperation, as will be readily understood.

Suitable pawls and racks or other locks may be provided to enable thelevers and 24 to be held in adjusted positions. On the upper shaft 5 ofthe excavator alongside the sprocket 9 a miter gear-wheel 25 is mountedand engages a corresponding gear 26, which is connected, by means of anendless sprocket-chain and sprocket-wheels or other suitable devices, toone shaft of an endless conveyer 27, located within a chute 28,communicating at its inner end with the upper end of the excavator 7 andadapted to receive the excavated earth from the buckets 8. The chute 28is arranged so as to project laterally beyond the box or bed 1, so as todischarge the earth taken up beyond the same and into a dirt-wagondriven alongside the excavator.

From the foregoing description, taken in connection with theaccompanying drawings, the construction and mode of operation of theinvention will be readily understood.

It will be seen that it provides an excavating apparatus which may bereadily mounted upon an ordinary vehicle-body and which may be cheaplyoperated, as it may be readilycontrolled by the driver of the vehicleand receives motion from the running-gear of the vehicle.

By the construction and arrangement of parts shown the device is easilyoperated and may be readily worked by a single team.

. Various changes in the form, proportion, and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of this invention.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

In an excavator and loader of the character described, the combinationwith a vehiclebody and its running-gear, of a sprocket- Wheel upon oneof the elements of the running-gear, an excavator mounted upon thevehicle-body and comprising upper and lower shafts, an endless conveyermounted on said shafts, a sprocket-Wheel on the upper shaft, a doublesprocket-gear disposed below the same, a chain connecting thesprocket-wheel on said upper shaft with one of the sprocket elements ofthe double sprocketgear, a traveling chain running over the othersprocket element of the double sprocket-gear, and having a portionmoving in contact With the sprocket-wheel on the running-gear of thevehicle, a delivery device actuated from the upper shaft of theexcavator, and means for moving the running chain into and out ofengagement with the sprocket-wheel on the running-gear, substantially asdescribed.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

JOSEPH SAMPSON.
